Analysis on the evaluation of urban greenway network construction with AHP method

With the planning and construction of greenway in domestic cities, "city greenway" has been integrated into the lives of the majority of citizens, and gradually presents a trend of diversification. That AHP method was used to analyze the construction and evaluation of the evaluation factor subset of greenway network infrastructure in Luogang Street, Guangzhou. The weight analysis of the evaluation factor subset after the completion of luogang street greenway network is completed by determining the components of the evaluation factor subset and the weight of each factor: P4-Overall greenway construction > P5-Investment in management and maintenance of greenway network after completion > P3-Supporting facilities along the greenway.

A methodological framework to create an urban greenway network promoting avian connectivity: A case study of Curitiba City

Integrating landscape models into urban planning can promote the use of green infrastructure tools in cities, which are essential for meeting future sustainability requirements. The city of Curitiba, the capital of Paraná State, Brazil, provides an opportunity to research methodologies related to habitat connectivity in urban areas. Our study aims to propose a network of greenways that connect the most ecologically relevant green areas. Our methodology integrates avian movement and environmental indicators to enhance urban ecology by leveraging the spatial characteristics of the landscape. In designing the path network, we adapted the parameters to fit the minimum cumulative resistance model, which was based on studies of birds in the urban environment and their dispersion behavior. Our findings indicated that impervious surfaces were the predominant land cover class in the city landscape, while larger forest fragments were primarily situated in the south and northwestern regions. By utilizing least-cost paths, we identified twenty-six priority areas that could be connected to form an ecological network spanning the landscape. Our analysis revealed that the path network was more densely distributed in peripheral areas, where the largest habitats were located, primarily within the city's green belt. Regarding land cover classes along the paths, we found that 39% consisted of forest, 25% of impervious surface, 19% of grass, 16% of bare soil, and 1% of water. Despite being highly urbanized, Curitiba possesses significant potential for restoring avian-related functional connectivity through the urban forest. To aid in the recovery and conservation of ecological corridors along the greenways, we developed a set of guidelines. The information gathered from this study may prove useful for future interventions in the city, and the proposed methodology could serve as a model for greenway planning in other urban areas.

Calculating and Mapping the Naturalness of Peri-Urban Greenways

Peri-urban forests often have extensive greenway networks that allow for outdoor recreation. However, information associated with these greenways often does not include their degree of naturalness, which is usually reduced to descriptions of the flora and fauna and often overlooks the factors that reduce naturalness. Therefore, in some cases, the naturalness of these greenways is lower than expected. Quantifying their naturalness would be helpful, especially for hikers interested in appreciating and enjoying nature. Additionally, this information would help outdoor recreation managers to design trails or decide which ones to promote as “greenways”. The objectives of this study are (1) to design a method to calculate and map the naturalness of greenways using two approaches, one based on perceptual fieldwork and the other on geographic information systems (GIS); (2) to apply the designed method to a specific greenway; and (3) to compare both methodological approaches. The results show that, for the greenway studied, the naturalness scores obtained are low in all three types of analyses used. Around 70% of the greenway sections in the GIS visibility analysis and 80% in the GIS proximity analysis have a low naturalness index. In comparison, this value is reduced to 40% with the fieldwork analysis. Although the results of the GIS approach (proximity and visibility) generate naturalness indices and spatial patterns that are very similar, they differ significantly from those derived from the fieldwork analysis. The discussion of the results suggests that the three methodologies used are valid for analyzing the degree of naturalness of the trails. However, if used together, it could add flexibility to the type of variables incorporated in the analysis.

PLUS GreeN: Reconciling Urban Streams and Greenways through Placemaking

Design and planning regarding urban streams are mostly viewed through the lens of ecological restoration the federal and state agencies. Cities and counties, undertaking the greenway and green network planning exercises mostly consider the urban streams as a sub-context, to be dealt with at a later stage or by different agencies. The middle ground between the urban streams, and urban greenways, thus often remains un-tended, and shows up as fragmented urban mosaic. Placemaking is often discussed in design and planning of architecture and landscape of urban built environment, to create a pause or interest or a place of rest for people. This paper considers placemaking as a landscape design approach to address the middle ground and reconcile the two ecologies of urban streams and greenways. A focused case research of an urban stream in northeast Baltimore is undertaken based on classic method of site-context analyses, federal, state, and local guides on stream restoration are considered and opportunities of bridging the connection are envisioned through conceptual design resolutions, underscored by the agenda of placemaking. As further research, the disconnect between various natural resources such as urban streams and urban greenways should be addressed through policies.

Reconnecting people to the Detroit River – A transboundary effort

Abstract Windsor in Ontario, Canada and Detroit in Michigan, USA are Great Lakes border cities on the Detroit River that have a long history of water pollution. Public outcry over water pollution in the 1960s led to the enactment of environmental laws starting in the early 1970s. As these laws were implemented and water quality improved, citizens started calling for improved public access to the river, including establishing linked riverfront greenways. This paper presents a case study of greenway development in these border cities based on indicator reporting to comprehensively assess ecosystem health. Findings show that waterfront greenways were catalyzed by cleanup of the Detroit River. As greenway systems expanded on both sides of the border, greenway stakeholders began to envision cross-border greenway connections that would stimulate ecotourism, help encourage healthy lifestyles, and enhance quality of life in southwest Ontario and southeast Michigan. Recommended next steps include investing in greenway capacity building, identifying and testing creative financing options for greenways, formalizing institutional arrangements between Canada and the United States for a binational greenway network, and strengthening cross-border greenway connections by reestablishing a cross-border ferry, offering free access to the tunnel bus on weekends for cyclists, and hosting Windsor-Detroit open streets’ events. Robust transboundary greenway partnerships are critical to realizing the full potential of cross border greenway systems, including expanding outdoor recreation and ecotourism, conserving natural resources, and inspiring a stewardship ethic for shared ecosystems.

Greenway Network: A Participatory Planning Approach for Municipalities of the South Region of Brazil

Abstract Development of greenways represent a planning strategy that seeks to reconcile both nature conservation and human uses. It is crucial for maintaining landscape connectivity in an increasingly anthropized world. Such strategy encompasses complex socio-ecological variables and its success greatly depends on the integration of different types of knowledge and active support from the local communities and stakeholders. This demands participatory planning processes within multidisciplinary platforms that promote a close collaboration between experts and lay people. The goal of this paper is to describe and analyse a participatory planning approach for the early-stage design of a greenway network for municipalities in South Brazil. The majority of southern Brazilian municipalities contain a very high rate of small farms which are under intensive agricultural production, and consequently, harming the natural landscapes. Actions to effectively tackle this problem are scarcely observed. The procedures encompassed by the approach were determined by the context constraints and potentials that make it applicable in the reality at stake. The approach is focusing on the early-stage design of a greenway network plan and comprises two phases with each a multi-stakeholder workshop for the local landscape analysis and the plan co-design by experts and local actors. The application of the approach in a municipality in southern Brazil has enabled local actors to use key concepts of connectivity planning and foster a critical reflection on local issues, and allowed the incorporation of local knowledge into the solution developed by participants. This resulted in a plan tailored to the local reality.

A greenway for sustainable transportation of the university campus: Diyala University as a case study

Transportation is one of the aspects that enable us to achieve sustainability on a university campus, by taking environmental, social, and economic requirements. Walking is a green mode that can be essential to promoting sustainable transport. This study aims to evaluate the ability of campus physical development planning at Diyala University in creating sustainable transport on campus by determining the problems that exist. The research problem was identified in the absence of a comprehensive view of the importance of greenway network connectivity in the sustainability of the campus and the most important barriers that prevent it from being achieved and the incentives to be activated. The methodology used in this study was the quantitative and qualitative approach, by observing the movement problems on campus and imaging as well as defining thermal hotspots using the GIS program, to active modes of transportation through various strategies. Findings revealed several issues on design solutions that related to three levels for campus’s greenways, the relationship of (paths-paths) and (paths-buildings) and (paths-landscape) and the identification of vital foci represented by the areas of intersection, movement, and stopping. Consequently, the framework for a guideline to develop this campus and any campus of similar characteristics. Finally, sustainable design for the University of Diyala has been developed.

Greenways in Athens, Greece:Enhancing connectivity through a greenway network in a contemporary European metropolis

ABSTRACT The Greenway Plan is a Network of green corridors, including open spaces and parks in Athens.Its objective is to bring together strategies for parks and urban landscapes, creating a novel andalternative vision of Athens Urban Web. The design approaches used in other countries have not been adopted in Athens as a matter of public urban policy and due to limited funds and lack of incentives. Since 2018, when the design was financed by Green Funds, the results were presented in 3 Athenian municipalities. This paper introduces innovative ecological and sustainable strategies that can be extended to whole Athens web.

A data-informed analytical approach to human-scale greenway planning: Integrating multi-sourced urban data with machine learning algorithms

Urban greenways have been recognized as an important strategy to improve human-scale quality in high-density built environments. Nevertheless, current greenway suitability analysis mainly focuses on geographical and natural issues, failing to account for human-scale urban design factors. Accordingly, this study proposes a data-informed approach to planning urban greenway networks using a combination of classical urban design theories, multi-sourced urban data, and machine learning algorithms. Maoming City in China was used as a case study. Per classical urban design theories, specifically, Cervero and Ewing’s 5D variables, density, diversity, design, dimensions of destination accessibility, and distance-to-transit, were selected as key factors. A series of new urban data, including points of interest (PoIs), location-based service (LBS) positioning data, and street view images, were applied in conjunction with machine learning algorithms and geographical information system (GIS) tools to measure these key factors at a human-scale resolution and generate an optimized greenway suitability analysis. This analytical approach is an attempt to take human-scale concerns into account on a city-wide scale regarding greenway network generation. It also pushes the methodological boundaries of greenway planning by combining classical urban design thinking with new urban data and new techniques.

Place-Making upon Return Home: Influence of Greenway Experiences

Recreation experience has long been studied for its close relationship to human health and personal development. Previous research focused mainly on the experiential and on-site outcomes. This study extends past research to explore the critical role of recreation experience on human development, particularly after people return home. To do so, an experiential-emergent-learning model of recreation experience is proposed and empirically experimented. Based on a participant-generated photo technique and a two-step interview protocol, support was provided for home-based behavioral changes as an enduring outcome of greenway experiences. Through tracking the interplay of recreationists’ greenway experience, self-development, and home place-making, the study illustrated a learning cycle between greenway experience and human-environment relationships. The implications suggest the potential of a greenway network for promoting pro-environmental behaviors and sustainable tourism.

Research on the Spatial Structure of County Greenway Network Based on Gravitation-Resistance Measurement—A Case Study of Ning’an in China

The ecological value, cultural value, economic value and industrial value of the county space, where a variety of human activities and natural ecological processes are carried out, act as the key elements considered in county spatial planning. However, there is a lack of carrying space for integrating these values in the actual Chinese county construction. In this article, the construction of a county greenway network is based on multiple needs, such as ecological protection, characteristic landscape, leisure and recreation. The ecological, cultural and economic values of resources are taken as the basis of identifying a greenway network. We establish the gravitation-resistance model to measure network flow based on the attraction and resistance between resources. In particular, by means of network flow analysis and the geographic information system (GIS), the resistance and gravity are assigned to the resources and landscapes, respectively. The attraction between elements is then measured using the gravitation-resistance model. The distribution of resources and the trend of integration are analyzed by the combination of the centrality of resources and the ratio of supply to demand. Based on the analysis results of network flow, the paper puts forward a strategy for developing a county greenway network, and improves the scientific evaluation of the spatial resource. It provides a new perspective for the construction of a county greenway network.

Can greenways perform as a new planning strategy in the Pearl River Delta, China?

The modern greenway movement in China originated in 2010 when Guangdong Provincial Government launched the Pearl River Delta greenway network. The PRD greenway planning has strategic objectives that respond to issues associated with urbanization in the region. This article presents a conceptual framework that explains the potential impact of several key factors in the planning context on the strategic uses of greenways. The framework is then applied to empirical research carried out in the PRD. The results show that greenway planning is a feasible strategy to promote rural economic development by attracting tourists and promoting the development of service sectors. In general, the PRD greenways function as a social strategy: they create new recreational spaces and provide public goods and facilities in both urban and rural areas. However, the results also show that many greenways lack landscape and ecological strategies and become primarily a transportation strategy that defines space for walking and cycling routes in urban areas. The emerging transportation-led greenways reflect the inconsistency of planning goals and outcomes, which is a compromise to both the centralized administrative system and the inadequacy of greenway resources. This article concludes that although strong leadership is necessary in greenway development, insufficient social participation can undermine the achievement of the goals and priorities of the greenway plan, particularly the ecological goals and functions. How to engage local agencies, interested groups, and affected stakeholders in the planning and decision-making process has become a big challenge for greenway planning in the PRD greenways.

Assessment of Green Infrastructure for Conservation Planning using Cadastral Data in Seoul, South Korea

Green infrastructure has been used for environmental conservation and management with many similar concepts such as green-space network, green-link network, and green-ways network based on the objectives of the cities for greening. Seoul established the 2030 Seoul City Master Plan that contains green-link network projects to connect critical green areas within the city. However, the plan does not have detailed analysis for the green infrastructure to incorporate land-cover information to many structural classes. This study maps green infrastructure networks of Seoul for complementing their green plans with identifying and ranking green areas. Hubs and links that are the main elements of green infrastructure have been identified through incorporating cadastral data of 967,502 parcels to 135 of land use maps using Geographic Information System. The study extracted 1,365 of green areas that represent an area of 24,530 ha within the city and buffered these areas to identify districts as critical green areas that have hubs and links. At a city scale, the study used 103,553 of parcel data for ranking extracted 20 districts, and 17,860 of parcel data for ranking extracted 42 links connecting the districts. At a district scale, this study used 87,826 of parcel data for analyzing the status of potential links within the districts and ranking these districts for green infrastructure. This assessment analyzes the main elements of green infrastructure and suggests site prioritization for green infrastructure under variable scenarios of green and developed areas in a metropolitan city.

Modeling potential tree belt functions in rural landscapes using a new GIS tool

The increasing human pressure on the environment requires effective protection activities. One way to stop the degradation of natural resources is the presence of woody vegetation networks, mainly linear in character, called linear woody features, greenways or tree belts. These objects, thanks to the many natural and economic functions they serve, enable the realization of sustainable development policy. To properly design a greenway network, the natural conditions and degree of environmental degradation in a given area must first be evaluated. Based on these data, it is possible to determine appropriate afforestation needs.To evaluate the ability of a given area to meet the requirements of greenway functions, we propose a new computer modeling system – a tree belt modeling (TBM). TBM defines the availability of tree belt functions in the planned network and is one of preparation stages in the design of an optimal greenway structure. In this work, to analyze the studied area potential, application of a cadastral dataset was proposed. Thanks to this approach, the obtained results may be related to specific plot borders, which is optimal for greenway construction. To automatize the process of analysis, the TBM was implemented into an ArcGIS toolbox. The result of using this toolbox is a tree belt functions geodatabase. This database contains information about the available functions in the analyzed lines that are potential sites for afforestation. This solution, both at the methodological and technological levels, may significantly increase the effectiveness of greenway planning and thus contribute to more effective activities for sustainable development.

The versatility of green infrastructure is a prerequisite for maximizing the overall benefits of urban ecosystem services, which has been recognized by many scholars. We have constructed a green infrastructure planning (GISP) model that includes functional indicators such as rain-flood management, green space accessibility, air purification, heat island mitigation, and landscape connectivity. It is used to conduct an assessment of the versatility of urban green infrastructure, identify high-demand areas for green infrastructure in Hefei, and explore trade-offs and synergies between different functions of green infrastructure. The results show that the northeastern part of Hefei City has the strongest demand for green infrastructure to alleviate urban heat island effect and clean air. The urban one-ring area has the strongest demand for rain-flood management of green infrastructure. The eastern and southern parts of the city have significant demand for green space accessibility. In general, the hotspots for green infrastructure site selection are within the urban area and the northeast region. There is a synergy between the rain-flood management, the alleviation of urban heat islands and the purification of air, and there is a trade-off between these three functions and the landscape connectivity. The GISP model is used to evaluate the Hefei ecological space system control plan and the Hefei spatial greenway network system construction general plan. The planned green space site selection is not in the high demand area of green infrastructure, and there is no strategic integration of green space multi-functional ecosystem services. Thereby obtaining greater ecological resilience. 参考文献 相似文献 引证文献
